I have my rhizomes in my fridge. I would plant them now, but I am moving in about one month. The plan is to plant them in pots and carfully transplant them at the beginning of June. My only real concern is that I need them to still fit in my car when I move them. How high will first year plants grow in one month? Should I wait a week or two, or just plant them now like I want to do so badly!!???!
